Tabby is a type of pattern common to domestic cats not a cat breed. Bengal is a breed of cat.The tabby cat has a distinctive coat that features stripes, dots, or swirling patterns, usually together with an "M" mark on its forehead. There are four tabby patterns that have been shown to be genetically distinct: mackerel, classic, spotted and ticked. Tabby are grey in colour whereas bengal normally are brown except the so-called silver bengals(cross breed between ALC or normal bengal with silver spotted american SH) which have white base with black/grey contrast spots/marble. Unless you have cert., it is domestic short hair tabby to me.
